No, the diameter of a circle is not 2 times the circumference. The correct relationship is that the circumference (C) is π times the diameter (D), expressed as C = πD. Conversely, the diameter is the circumference divided by π.

FAQs & Answers

  1. What is the diameter of a circle? The diameter of a circle is the distance across the circle through its center, and it is twice the length of the radius.
  2. How do you calculate the circumference of a circle? The circumference of a circle can be calculated using the formula C = πD, where D is the diameter of the circle.
  3. What is the value of π (pi)? The value of π (pi) is approximately 3.14159, which is a constant that represents the ratio of a circle's circumference to its diameter.
  4. Can the diameter be calculated from the circumference? Yes, you can calculate the diameter from the circumference using the formula D = C/π.
